Is there a standard for the amount of play in the square cushions of the dog bone mounts? I was watching the mounts move while I was replacing my s.c. tensioner, not sure if what I'm seeing is considered "normal". (2001 GTP)
you mean the upper radiator mounts? The big square rubber ones? you woudl be surprised how much PLAY they have. If you ever have your car dynoed, you will think your engine just broke with how much if moves when you go WOT! That is why many people get the poly upper mounts to limit that PLAY. How much is too much? Hard to say. Look at your mounts and if they look worn or torn, replace them.
